How to determine if my Sonos system is using the Sonos mesh network and not home WiFi

The two devices last in the ‘About’ list , the Workshop P3 and ZP80, are in my shed, 800 meters from the house.

House to shed is connected via a Deliberant Point to Point secure wireless bridge, with a WiFi Access Point in the workshop, with same SSID as at home.

If the whole system switched to SonosNet, the Workshop end would stop working I’d guess as there are no wired components in the workshop. The ZP80 and P3 are WiFi with no wired SonosNet devices in range.

At the home end of the system, the BR100 bridge is hard wired to the router and ZP90 is wireless, connected via WM0 SonosNet... but the two Play1’s stay on WiFi WM1 mode

All working fine, just interested in your thoughts really, as I had heard that it was supposed to exclusively WM0 or WM1 only

Is there a WM2 ? What is that ?

WM:2 is for speakers attached as surrounds to Playbar or Playbase and indicated connection via 5GHz.

As I said you can have a Sonos SYSTEM that runs a mixture of SonosNet AND Wi-Fi. And your shed would NOT stop working if all the other devices were using SonosNet. This is because the SonosNet and your Wi-Fi are essentially the same network so the devices can are all connected together even if only 1 is using Wi-Fi. Now, if you removed the Wi-Fi credentials from Sonos then the device in the shed would probably be too far away from another Sonos unit providing SonosNet so then it WOULD stop working.

But what they are most assuredly NOT doing is connecting to the network via the 2 networks simultaneously.

OK, I was not imagining that any Single device was using both at the same time,

But some devices can be on WM0 while others still on WM1
Every device now playing, some showing SonosNet and some WiFi

The workshop ones (ZP80 & P3 ) are 800 meters from the house, nothing wired there, and well out of range of the wired Bridge in the house They can never connect via SonosNet, as they are too distant, but happily stay on WiFi

Thanks Stuart, that was what I was seeing.

Thanks

Hi! Still find this confusing. Sonosnet and Wi-Fi units use the same ip address space. So how does sonosnet actually work?

The WiFi protocol Sonosnet uses is a proprietary Layer 2 protocol, but it still uses standard Layer 3 IP networking. This means all Sonos devices must still use standard lP addresses.

Hi! Still find this confusing. Sonosnet and Wi-Fi units use the same ip address space. So how does sonosnet actually work?To do this justice I would have to start talking about networking 'layers', but in essence, when SonosNet is running, there are two segments to your home LAN, as far as data transmission is concerned. Sonos devices pass data to each other using SonosNet (a patented wireless technology that uses mesh networking). Other devices pass data using wifi (a different wireless technology, which may use mesh networking but traditionally didn't). In order for data to flow between the two wireless segments, a wired connection is needed.

That is all just about how data flows. It is all still one network, with IP addresses handed out by your router. Everything HAS to be on the same network, indeed subnet, for everything to be able to talk to everything else.

Does that help a bit?

Sure! Thanks for the explanation. One more thing. Having a 5.1 setup plus some Ones in other rooms, wiring one of the single Ones creates a Sonosnet as expected. All speakers in the 5.1 setup now shows WM 0. But if I disconnect Ethernet and they revert back to Wi-Fi all speakers except Sub and surrounds show WM 1 and the surrounds and Sub shows WM 2. This is expected too since WM 2 is the distinguishable 5ghz connection used in a 5.2 setup. Why when using Sonosnet isn’t this difference reflected as it is when using Wi-Fi?
